COTTON-SEED HULLER AND SEPARATCR.

sPEoInIcATIon forming- Z'o all whom it may concern:

. Be it known that we, JAMES S. ZERBE and i ANDREW J. Wnnabntnof Cincinnati, inthe improvement is fully set forth in the following- SPQCIfiOZLtlOH and accompanying drawings, in which 'county of Hamilton and State of Ohio, have invented a new and useful Improvement in Gotton-Seed Hullcrs and Separators, which Figure 1 is an end view of our cotton-seed huller. Fig.2 is a front view of the same.

Fig. 3 is an enlarged cross vertical section of the feeding and hulling, box; Fig. A, a perspective view'of 'the hulling cylinder or roll; Fig. 5, a perspective view of the concave and ribs; and Fig. 6,a front View, partly in section,

of the hulling-rolland shaft, showing the solid boxing in which it is journaled.

The object of the present invention is to pro- 1 vide a cheap and efficient machine for hulling cotton-seed and separating the same; and it comprises, among other parts, a solid roll provided with ribs operating within a casing, which has concaves, upon which are ribs, so that as the cotton-seed is fed into the rolls by means of a feed-roll the ribs split the seed and permit the germ tobe separated from the hulls.

The seed, asit passes from the roll, falls into a conveyer, which rotates within a perforated concave shell, thus separating the germ from the hulls, thelatterpassing into a suctionfan,

from which it is expelled through tubes into the furnace, or to some convenient point away from the machine.

In the accompanying drawings, A represents the main frame, which carries the l1ulling-roll and case B. The frame 0 supports the rear same purpose.

end of the perforated casing D, within which the screw-conveyer E operates. The frame A supports the forward end of the casing D.

The casing F B O J which contains the hulling and feeding rolls, is of peculiar construction, and it is in this, among otherrespects, that this machine is superior to others for the The base F, which forms the end pieces for the hopper or case, has i journaled therein the shaft G of the hulling-roll. Instead of providing adjustable boxing, as is customary in machines of this class, we conperforated part of Letters Patent No. 289,365, dated November 27, 1,883,- Application filcd September 24, 1883. (No model.)

' struct asolid b0Xing,I-I, larger thanthe shaft,

and after the shaft is placed in the boxing and properly adjusted, Babbitt metal 1 I is run around the shaft. By this means no other adjusting is required, and the roll will be firmly held in position. The shell J of the casing on the rear side conforms to the arc of the roll K within. 011' the forward side we place two concave pieces, L L, each of which is provided with two or more ribs, M, which will be fur ther explained hereinafter in connection with the roll K. Above the hulling-roll K is the feed-roll N. It willbe observedthat the front face, 0, at the upper part of the casing, is exactly vertical and onthe same plane. as the shaft G of the hulling-roll. The feed-rollNis located within the casing, so that its periphery touches the side 0, while the side I? of the case is of the same are as the roll, and extends over to a point, P, directly above the shaft N of the feed-roll, from which point the side Q extends upwardly and rearwardly, so as to form a hopper or receptaclefor theseed. It will be observed that the feed-roll N turns to the left, or in the direction shown by the dart, The roll N being corrugated, as shown at R, the seed will fall therein, and as the seed tends to fall to the right against the vertical side 0 of the casing, the turning of the roll has a tendency to constantly raise the seed and loosen the same, so that when any point or rib of the roll reaches the corner P the pressure of the mass of seed above will not cause the seed to crush between the roll and the casing and choke the machine or ballthe seed. WVe find proper feeding to be an important matter, especially where the seed has not been perfectly linted; but by the arrangement here shown the most perfect feeding is accomplished, and there is noliability of choking.

Referring now to the hulling-roll K, it will be seen that in this instance six ribs, a, are shown,

equidistant apart. These ribs 112 ve their edges 12 projecting out, preferably, about one-eighth of an inch, or slightly less, and a straight line is drawn from the base of one rib to the base of the next, as shown at c. Theconcave pieces L on the forward side of the casing have on their inner surfaces two or more ribs, M. These ribsare about an eighth of an inch in height,

and the spaces L between the ribs are concaved, so that the spaces formcdby the straight faces 0 of the roll K and the concave plat-es L will furnish sufficient draft to take in the seed as rapidly as it is fed to the hulling-roll.

Ve also call particular attention to the fact that the hulling-roll K and the ends of the casing Fwhieh receives the concave plates L, are of the same are, and since the ribs M of the concave plates are flush with its end surface, M, the plates L, when placed on the case F and bolted thereto, require no other adj ustment.

Below the hullingroll is the conveyer-box D, perforated as shown,within which is placed the scrcw-convcyer E. At the rear end of the machine is a suction-fan, S,which is designed to receive the hulls and convey themeither to the furnace or remove them to some con-1 venient point away from the machine.

To operate the mechanism we provide a counter-shaft, T, on the frame A, and by means. of the belts U V and their pulleys transmit the speed necessary to rotate the feed-ro1l N; 21150,} by means of the belt XV, motion is transmitted; to the SCIGW-O01'lVGyCl E.

It is obvious that the feed roll and conveyer,

1. The hereindescribed hulling-roll,which consists of a solid roll, K, having slightly-proj ecting ribs a and intervening straight spaces 0, substantially as herein set forth.

2. The herein-described concave, consisting of plates L, having the ribs M, the flush-surfaced ends M, and the concave intervening spaces L, substantially as described.

3. The combination of the solid roll K, having ribs a and straight spaces 0, with the concave plates L, substantially as described.

4. The combination of the hulling-roll K and the casing FB 0 J, the rear part, J, conforming to the arc of the roll ,with the concaved pieces L, having ribs hi and flush surfaced ends M, substantially as described.

5. The combination of the hulling-roll and concave with the fluted feed-roll N and seed hopper having a vertical front face, 0, in

clined upper rear face, Q I and the curved outwardly and downwardly extending lower rear face, P, substantially as described.

In testimony that we claim the foregoing we have hereunto set our hands this 18th day of September, 1883, in the presence of witnesses. 55
